SMP kernel supports multiple processors so you don't need it. I'm not sure bout HT but most likely normal kernel should support it too (maybe not the stock kernel supplied with the distribution - compiled 'by hand' kernel is always the best choice anyway)

Hyper-Threading is indeed enabled in the BIOS. Check your BIOS manual for more information.

Boldywn, if he wants to get optimal performance with Hyper-Threading active he needs to use the SMP kernel; otherwise the performance will be poor. As for compiling his own kernel, he really shouldn't do that unless the newest kernel (2.4.23) does HT better than the vendor kernel he's using.

TheOneKEA: you're right about SMP kernel and HT, like I said - I wasn't sure. However I don't agree with your kernel opinion. Distribution-supplied kernels are compiled for a broad range of configurations and have no CPU-specific optimization. If you compile the kernel yourself, you can tweak it to your hardware, compile it for the specific architecture and reduce its size - which results in faster work.

ok , but don't expect me to know how to do it....

once i tried to install gentoo , after many battles i could compile the kernel and boot it , but i got so many errors ...

Most likely you didn't compile some necessary drivers... My first kernel compile ended in lots of errors and kernel panic too Anyway, custom kernel is a nice thing to have, but you can live without it. There are lots of kernel-compile-howtos and it's always worth to learn something new

Certainly. I understand that too; using a vendor kernel in lieu of a custom kernel tailored to your system is a poor choice, unless you are unable or unwilling to compile said custom kernel.

Thats not true for SuSE which installs a Athlon/Intel optimized kernel, I have k_Athlon kernel as it picks up your CPU architecture when you install suse.
